Biceps, triceps, glutes—these are the muscles that garner the most love. No one’s saying they’re not important, but there are smaller, less buzzy areas that are asking for attention in a total-body workout. And developing them can reap benefits, for both strength and body function. We’re talking about the highlighted ones below: 1) rotator cuff, 2) lower traps, 3) serratus anterior, and 4) gluteus medius.
“These four muscles control the range of motion of certain joints,” says Jon-Erik Kawamoto, a trainer in St. John’s, Newfoundland, in Canada. “Weaknesses in them can lead to faulty movement mechanics.”
Do these moves weekly, either for warming up or in the middle of a total-body workout. After a few weeks, you’ll be lifting heavier, adding reps to pullup sets, running farther—and doing it all better.
